(Embodiment 1)
The termite-proof structure that can solve the above problems has a plurality of fiber aggregates 4 arranged between the foundation concrete structure 2 of the building and the pipes 3 buried in the concrete structure 2. The termite-proofing structure 10 is characterized in that there are a plurality of first seams 5 whose longitudinal ends face each other, and the plurality of first seams 5 are arranged so as to be discontinuous. The first seam 5 is a portion where the ends of the fiber aggregate 4 face each other, and is a portion where it is relatively easy for termites to create an ant trail. Since the fiber aggregate 4 is arranged so that the plurality of first seams 5 are discontinuous, the first seams 5 of adjacent fiber aggregates 4 are located at separate positions. Therefore, even if termites invade along the first seam 5 of the fiber aggregates 4, the first seam 5 of the adjacent fiber aggregates 4 is located at a distance from the first seam 5, so the progress of the termites is dammed. This will prevent termites from invading further. Moreover, since the plurality of fiber aggregates 4 are arranged between the basic concrete structure 2 and the piping 3 in multiple steps, construction can be easily performed.

FIG. 1 is a side view (partially sectional view) showing an anti-termite structure according to an embodiment of the present invention. It shows how fiber aggregates are placed between the piping of a building and the basic concrete structure.

(a) and (b) of FIG. 2 are enlarged views showing an embodiment of a fiber aggregate disposed between a basic concrete structure and piping in the termite-proof structure shown in FIG. 1. FIG. 3(a) shows an embodiment of the first seam different from FIGS. 2(a) and 2(b). FIG. 2(c) shows the shape of the fiber aggregate shown in FIGS. 2(a) and 2(b) when viewed from the direction of arrow A. FIG. 3(b) shows the shape of the fiber aggregate shown in FIG. 3(a) when viewed from the direction of arrow A.

The foundation concrete structure 2 refers to the part that supports the vertical load due to the building's own weight and the horizontal load applied by earthquakes and wind at the lowest part and transmits it to the ground. As the structure of the foundation concrete structure 2, there are generally a cloth foundation used for normal hard ground and a solid foundation used for relatively soft ground, but the termite prevention structure 10 according to the embodiment of the present invention In implementing this, the structure of the foundation concrete structure 2 is not particularly limited, and may be any structure.

The piping 3 is a pipe laid to transport gas or liquid such as gas or water. In the termite-proof structure 10 according to the embodiment of the present invention, the type of pipe used for the pipe 3 is not particularly limited, and for example, a pipe made of polyvinyl chloride resin, polyethylene resin, polypropylene resin, stainless steel, etc. You can select it as appropriate.

The fiber aggregate 4 is a relatively flexible mass made up of elongated thread-like fibers. As the material constituting the fiber aggregate 4, organic fibers such as cotton, hemp, polyamide, polyester, and acrylic, and inorganic fibers such as glass fiber, rock wool, and slag fibers can be used. It is preferable that the fiber aggregate 4 is an inorganic fiber aggregate made of inorganic fibers, and it is more preferable that the fiber aggregate 4 is glass wool or rock wool. Thereby, the heat resistance and corrosion resistance of the fiber aggregate 4 can be improved.

The fiber aggregate 4 may be formed into an appropriate size and shape, but may also be cut into an appropriate size and shape. The shape of the fiber aggregate 4 is not particularly limited and can be plate-shaped, columnar, rod-shaped, etc., but in order to prevent gaps from forming between the foundation concrete structure and the piping, As shown in a), (b), and (c), and (a) and (b) of FIG. 3, the fiber aggregate 4 is more preferably plate-shaped.

As shown in FIG. 1, it is preferable that the fiber aggregates 4 are arranged so that the longitudinal direction of the fiber aggregates 4 is parallel to the circumferential direction of the piping 3; They may be arranged at an angle with respect to the circumferential direction. Parallel to the circumferential direction of the pipe 3 herein means within ±10° of parallel to the substantial circumferential direction of the pipe 3.

The first seam 5 refers to a portion where the ends of the fiber aggregate 4 in the longitudinal direction face each other. The first seam 5 may be such that the longitudinal ends of one fiber assembly 4 face each other, or the longitudinal ends of one fiber assembly 4 and the other fiber assembly 4 may face each other. The longitudinal ends may be opposite to each other. Specifically, for example, when the fiber aggregate 4 is plate-shaped as shown in FIGS. 1, 2(a), (b) and (c), and 3(a) and (b), , the portion where the surfaces facing each other at both ends in the longitudinal direction are called a first seam 5.

The first seam 5 of adjacent fiber aggregates 4 of the termite-proof structure 10 according to the embodiment of the present invention is discontinuous. A state in which the first joints 5 are discontinuous is, for example, as shown in FIG. (sometimes a plurality of first seams are in different positions), a state in which the first seams 5 of adjacent fiber aggregates 4 are not connected, a state in which the first seams 5 of adjacent fiber aggregates 4 are separated It is possible to say that a state in which something is happening is discontinuous.

The first seam 5 of adjacent fiber aggregates 4 of the termite-proof structure 10 according to the embodiment of the present invention is discontinuous. As shown in FIG. 2(a), all the first seams 5 of the fiber aggregates 4 arranged between the basic concrete structure 2 and the pipe 3 are located at different positions around the pipe 3 when viewed from the direction of the arrow A. However, as shown in FIG. 2(c), when the fiber aggregates 4 are viewed from the direction of arrow A, the first seam 5 of adjacent fiber aggregates 4 is the center of the circle of the pipe 3. It is preferable to arrange it on the arc of 1/4 circle in front and back of position 3b which is symmetrical with respect to 3a, it is more preferable to arrange it on the arc of 1/8 circle in front and behind 3d, and it is arranged on the arc of 1/16 circle in front and behind. It is more preferable to arrange it on the arc 3e. With the above configuration, even if termites invade along the first seam 5, the course of the termites can be blocked by the fiber aggregate 4 that is next to the fiber aggregate 4, and Since the path that termites travel to the first seam 5 of the fiber aggregate 4 adjacent to the seam 5 can be made longer, the invasion of termites can be more reliably prevented.

As shown in FIGS. 2(b) and 2(c), when viewed from the direction of arrow A, the first seams 5 of adjacent fiber aggregates 4 are arranged at positions 3b symmetrical with respect to the center 3a of the circle of the piping 3. It is particularly preferred that the When the first seam 5 of adjacent fiber aggregates 4 is arranged at a symmetrical position 3b with respect to the center 3a of the circumference of the pipe 3 when viewed from the direction of arrow A, the first joint 5 of the fiber aggregates 4 The distance from the seam 5 to the first seam 5 of the adjacent fiber aggregate 4 can be fixed to half the circumference of the pipe 3. Even if termites invade along the first seam 5, the path the termites travel to the first seam 5 of the fiber aggregate 4 adjacent to the first seam 5 can be made longer, so it is more reliable. It can prevent termite invasion.

The shape of the first joint 5 may be configured to be perpendicular to the circumferential direction of the piping 3 like the first joint 5 shown in FIGS. 2(a) and 2(b); Like the first joint 5 shown in (a), it may be configured to have an inclination with respect to the circumferential direction of the pipe 3. If the first joint 5 shown in FIG. 3(a) is configured to have an inclination with respect to the circumferential direction of the pipe 3, the first joint 5 shown in FIGS. 2(a) and (b) The path L of the first joint 5 can be made longer than if it were configured to be perpendicular to the circumferential direction of the pipe 3. In this way, by lengthening the path L of the first seam 5, termite invasion can be more reliably prevented. The path L of the first seam 5 refers to the path from one end of the first seam 5 to the other end. Further, although the first seam 5 shown in FIGS. 2A, 2B, and 3A is straight, it may have a curved or wavy shape. With this configuration, the path L of the first seam 5 can be made longer.

A heat insulating material 6 is arranged outside the basic concrete structure 2, and a plurality of fiber aggregates 4 are arranged between the heat insulating material 6 and the piping 3 buried in the heat insulating material 6. Preferably, the termite-proofing structure 20 has a plurality of first seams 5 whose longitudinal ends face each other, and the plurality of first seams 5 are disposed discontinuously. Since the plurality of first seams 5 are disposed discontinuously, the first seams 5 of adjacent fiber aggregates 4 are located at separate positions. Therefore, even if termites invade along the first seam 5 of the fiber aggregates 4, the first seam 5 of the adjacent fiber aggregates 4 is located at a distance from the first seam 5, so the progress of the termites is dammed. This will prevent termites from invading further. Moreover, since the plurality of fiber aggregates 4 are arranged between the basic concrete structure 2 and the piping 3 in multiple steps, construction can be easily performed. Furthermore, since the installation area of the fiber aggregate 4 increases by the thickness of the heat insulating material 6 provided in the basic concrete structure 2, it is possible to make it more difficult for termites to invade.

FIG. 4 is a side view (partially sectional view) showing the termite prevention structure according to the embodiment of the present invention. It shows a state in which a fiber aggregate is arranged between a heat insulating material and piping installed outside the basic concrete structure of a building.

Further, as the heat insulating material 6 used in the termite prevention structure 20 according to the embodiment of the present invention, it is preferable to use a pasted heat insulating material rather than a sprayed heat insulating material.

In the termite prevention structure 20 according to the embodiment of the present invention, the fiber aggregate 4 disposed between the heat insulating material 6 and the piping 3 is formed by the longitudinal ends of the fiber aggregate 4 facing each other. Regarding the first joint 5, please refer to the explanation about the fiber aggregate 4 and the first joint 5 arranged between the basic concrete structure 2 and the piping 3, which are described in the explanation about the termite-proof structure 10. can.

It is preferable that the fiber aggregates 4 in the termite prevention structures 10 and 20 according to the embodiments of the present invention are arranged parallel to the circumferential direction of the pipe 3, and the longitudinal direction of the fiber aggregates 4 is parallel to the circumferential direction of the pipe 3. More preferably, they are arranged in parallel. By arranging the fiber aggregate 4 parallel to the circumferential direction of the pipe 3, the fiber aggregate 4 is arranged substantially perpendicular to the direction in which the pipe 3 extends, which is a direction in which termites do not want to advance. Can be done. This makes it possible to more reliably prevent the invasion of termites. Parallel to the circumferential direction of the pipe 3 herein means within ±10° of parallel to the substantial circumferential direction of the pipe 3.

In the termite prevention structures 10 and 20 according to the embodiments of the present invention, it is preferable that three or more fiber aggregates 4 are arranged consecutively, and three or more fiber aggregates 4 are arranged continuously without gaps. It is particularly preferred that the By arranging three or more fiber aggregates 4 in succession, even if termites invade along the first seam 5 of the fiber aggregates 4, other fiber aggregates 4 will prevent the termites from entering. By closing the end of the advanced first seam 5 without any gaps, it is possible to prevent the termites from advancing to the next first seam 5, so that the invasion of termites can be more reliably dammed. .

In the termite prevention structures 10 and 20 according to the embodiments of the present invention, three or more fiber aggregates 4 are arranged in succession so that the longitudinal direction of the fiber aggregates 4 is parallel to the circumferential direction of the piping 3. It is preferable, and it is particularly preferable that three or more fiber aggregates 4 are arranged in succession without gaps so that the longitudinal direction of the fiber aggregates 4 is parallel to the circumferential direction of the pipe 3. By arranging three or more fiber aggregates 4 in succession so that the longitudinal direction of the fiber aggregates 4 is parallel to the circumferential direction of the pipe 3, the fiber aggregates 4 can penetrate along the first seam 5 of the fiber aggregates 4. Even if there are termites that have left the termites, the other fiber aggregates 4 will close the end of the first seam 5 where the termites have progressed without any gaps, preventing the termites from trying to advance to the next first seam 5. Since it is possible to prevent termite invasion, it is possible to more reliably dam up the invasion of termites.

It is preferable that the heat insulating material 6 of the termite prevention structure 20 according to the embodiment of the present invention is harder than the fiber aggregate 4. With the above configuration, the fiber aggregate 4 can be arranged between the piping 3 and the heat insulating material 6 with less gaps. The hardness of the heat insulating material 6 and the fiber aggregate 4 is compared by measuring the Rockwell hardness of each and comparing the values. Rockwell hardness is measured according to JIS K 7202-2 method.

In the termite-proof structures 10 and 20 according to the embodiments of the present invention, for example, foundation concrete is poured around piping 3 whose surface is surrounded by fiber aggregates 4, and the fiber aggregates 4 are made to flow under the weight of the foundation concrete structure 2. It can be formed by hardening the basic concrete structure 2 while pressing. In addition, the above-mentioned termite prevention structure 10 and termite prevention structure 20 are constructed by forming a basic concrete structure 2 in which a hole is made for installing a pipe 3, and then passing the pipe 3 through the hole. The fiber aggregate 4 can also be arranged so as to be packed between the hole and the pipe 3. When packing the fiber aggregates 4 between the holes in the basic concrete structure 2 and the pipes 3, it is more preferable to forcefully push them. Similarly, in the case of the termite-proofing structure 20 in which the fiber aggregate 4 is arranged between the piping 3 and the heat insulating material 6, after forming the heat insulating material 6 with holes for installing the piping 3, the piping 3 is inserted into the hole. It is also possible to arrange the fiber aggregate 4 to be packed between the hole in the heat insulating material 6 and the pipe 3. It is more preferable to forcefully push the fiber aggregate 4 between the hole in the heat insulating material 6 and the pipe 3.

In the termite prevention structures 10 and 20 as described above, the relatively flexible fiber aggregate 4 is arranged between the basic concrete structure 2 and the piping 3. Therefore, even when an external force such as an earthquake is applied, the fiber aggregate 4 will not be cracked or damaged. Further, by utilizing the flexibility of the fiber aggregate 4 itself, it is possible to prevent a gap from forming between the basic concrete structure 2 and the pipe 3. By using the termite-proof structures 10 and 20 as described above, termite invasion can be continuously prevented for a long period of time without chemical treatment.

(Embodiment 2)
The termite-proof structure that can solve the above problems is one in which a plurality of fiber aggregates 4 are arranged between the heat insulators 6 placed outside the basic concrete structure 2 of the building. The termite-proofing structure 30 is characterized in that there are a plurality of first seams 5 in which the longitudinal ends of the first seams 5 face each other, and the plurality of first seams 5 are disposed discontinuously. . Since the plurality of first seams 5 are disposed discontinuously, the first seams 5 of adjacent fiber aggregates 4 are located at separate positions. Therefore, even if termites invade along the first seam 5 of the fiber aggregates 4, the first seam 5 of the adjacent fiber aggregates 4 is located at a distance from the first seam 5, so the progress of the termites is dammed. This will prevent termites from invading further. Moreover, since the plurality of fiber aggregates 4 are arranged between the heat insulating materials 6 in a plurality of times, construction can be easily performed.

The first seam 5 may be such that the longitudinal ends of one fiber assembly 4 face each other, or the longitudinal ends of one fiber assembly 4 and the other fiber assembly 4 may face each other. The longitudinal ends may be opposite to each other. Specifically, for example, when the fiber aggregate 4 is columnar as shown in FIGS. 5 and 6, the surfaces at both ends in the longitudinal direction, that is, the portions where the bottom surfaces face each other, are the first seam 5. call.

Although the first seam 5 shown in FIGS. 5 and 6 is substantially horizontal and linear, it may also have a shape that is inclined with respect to the horizontal direction, a curved shape, or a wavy shape. With this configuration, the path for termites to move in the first seam 5 can be made longer, so that invasion of termites can be more reliably prevented.

It can definitely be prevented. Parallel to the height direction of the building here means within ±10° of parallel to the substantial height direction of the building. When the fiber aggregate 4 is in the shape of a square prism or a plate, arranging the main plane of the fiber aggregate 4 so that it is parallel to the main plane of the concrete structure 2 also makes it difficult to create gaps where ants can enter. Therefore, it is preferable.

It is preferable that the heat insulating material 6 of the termite-proofing structure 30 according to the embodiment of the present invention is harder than the fiber aggregate 4. With the above configuration, the fiber aggregate 4 can be arranged between the heat insulating materials 6 with less gaps.
